BLOWGUN.

Application tiled May 21,

This invention relates to improvements in blow-guns and arrows therefor,and has for its object the improvement of the interior of the blow-gunwhereby improved results of blow-guns are obtained by eliminating muchof the friction that has heretofore exlsted in such apparatus.

A second object of the invention is to facilitate the manufacture of thegun and .render it' cheaper than similar Aguns heretofore made.

With these and other objects in View which will be apparent as thedescription proceeds, I will now describe my invention 1n connectionwith the accompanying drawinvs in which o Figure 1 is an elevation ofthe gun. Fig. 2 is a sectional view throughvthe gun showing the arrowtherein.

Fig. 3 is a cross section of the gun on the line 3-3 of Fig. 1, and,

Fig. 4 is a view of an arrow for use in the v un.

1 denotes the exterior portion of the blowgun barrel which may be madeof tin or steel preferably covered with paper which may be wrapped onthe blow-gun in layers as shown in 1. I referably coat the exterior ofthe plalip'er with afinishing varnish, although t 's is not essential.

On the exterior of the blow-gun I form a corrugated section 2 either bycorrugating the tube or inserting a corrugated section as indicated inFig. 2. 3 denotes the shank of 5 an arrow having the usual arrow headand si tion what 1926. Serial No. 110,761.

fibrous attachment 4 at its rear end. This fibrous end 4 preferablyabuts against a collar 5 on the shank 3 of the arrow and the fibers areattached in any suitable manner, as for example, as is clearly shown inthe 4o patent to IVhite 186,651. The fibers must be suiiicient in volumeto completely fill the interior of the tube 1 as shown in Fig. 2.

I have found that the corrugations 2 on the interior of the .blow-gunare of great advantage in combination with a fibrous head such as shownin Figs. 2 and 4, especially when they are of screw-threaded shape asshown in' Fig. 2 and improved result-s are obtained with the corrugatedbarrel, and bei 5o sides, the corrugations add to the rigidity of thetubes. i

The arrow 3 may be of wood orsteel, the wooden arrow being preferablyuseful as a toy while the steel arrow may be operated as a weapon.

Having Iparticularly described the invenclaim as new is:

1. A blow-gun comprising a barrel having corrugations on its intheriorand an areo row having at its rear a fibrous portion filling theinterior of the barrel.

2. A blow-gun comprisinga barrel coated on its exterior with paper andsaid barrel having corrugations on its interior in como5 bination withan arrow having a fibrous ortion to snugly fit within the corrugatlonson the interior of the barrel.

In testimony whereof I ax my signature.

WILLIAM DE CAVIN.
